Everything Marx said was based on established fact. He didn't predict anything, he didn't tell anyone that this is how a capitalist economy will work in the future, but rather this is how a capitalist economy works in growth and recession. And as the current economies in the western world work in the same way now as they did then because they're all based in capitalism, Marx continues to have fact on his side.
